Question

The temperature of water at the bottom of a waterfall is higher than that at the top because ________.

• A. water at the bottom has greater potential energy
• B. the surface at the bottom provides heat
• C. kinetic energy of falling water is converted into heat
• D. falling water absorbs heat from the surroundings

Answer 1

The correct option is C kinetic energy of falling water is converted into heat

According to conservation of law of energy, energy can be converted from one form to another without getting destroyed and created. When water falls from waterfall, the kinetic energy of water reaching the bottom gets converted into heat energy which rises the temperature of water at bottom.
